Hint: You will have to use the chain rule by finding the derivative of the argument and multiplying it by the derivative that results without the chain rule. Are you aware of how to use the Chain Rule? If not, then I'll provide a solution.

Rewrite f(x): \(\Large f(x)=ln\frac{1+\sqrt x}{1\sqrt x}=ln(1+\sqrt x)ln(1\sqrt x) \) now just take the derivatives of each ln separately....
